    摘要: A magnetic resonance imaging (MRI) system, comprising a magnetics system having a plurality of magnetics components configured to produce magnetic fields for performing magnetic resonance imaging, electromagnetic shielding provided to attenuate at least some electromagnetic noise in an operating environment of the MRI system, and an electrical conductor coupled to the electromagnetic shielding and configured to electrically couple to a patient during imaging of the patient by the MRI system. The magnetics system may include at least one permanent B0 magnet configured to produce a B0 magnetic field for an imaging region of the MRI system. The B0 magnetic field strength may be less than or equal to approximately 0.2 T.

    摘要: A method of producing a permanent magnet shim configured to improve a profile of a B0 magnetic field produced by a B0 magnet is provided. The method comprises determining deviation of the B0 magnetic field from a desired B0 magnetic field, determining a magnetic pattern that, when applied to magnetic material, produces a corrective magnetic field that corrects for at least some of the determined deviation, and applying the magnetic pattern to the magnetic material to produce the permanent magnet shim. According to some aspects, a permanent magnet shim for improving a profile of a B0 magnetic field produced by a B0 magnet is provided. The permanent magnet shim comprises magnetic material having a predetermined magnetic pattern applied thereto that produces a corrective magnetic field to improve the profile of the B0 magnetic field.
